I have been able to make out the following geographical forms 

 of this widely distributed species : — 



(i) Brachyspiza capensis {Muller). (Venezuela to Paraguay and 

 Argentina.) 



(2) Brachyspiza capensis insularis Ridgzvay. (Curasao.) 



(3) Brachyspiza capensis peruviana (Lesson). (Peru to southern 

 Mexico.) 



(4) Brachyspiza capensis chilensis {Meyen). (Chili.) 



(5) Brachyspiza capensis canicapilla {Gould). (Southern Patagonia.) 



Pyrgita peruviana Lesson, Rev. Zool. 1839, 45' ^^ apparently 

 the earliest name for the form which Dr. Allen separated under 

 the name Zoiiotrichia capensis costaricensis (Bull. Am. Mus. Nat. 

 Hist. Ill, 1891, 375). I have carefully compared specimens from 

 the two type localities (Lima. Peru, and San Jose, Costa Rica), 

 and have been unable to discover any material difference. Frin-
